Cognitive encapsulation of group meetings

ABSTRACT

An embodiment includes identifying which of a plurality of participants of a web conference is an identified participant associated with a selected cluster of a plurality of clusters of audio feed data of an audio feed of the web conference based on a self-introduction in the selected cluster. The embodiment also generates a first preliminary leadership score for the identified participant based on a speaking duration value associated with the identified participant and generates a second preliminary leadership score for the identified participant using a selected video segment as an input for a machine learning classifier model. The embodiment calculates a final leadership score for the identified participant based on the first and second preliminary leadership scores. The final leadership score is representative of a likelihood that the identified participant is a supervisor, and is indicative of the identified participant being a supervisor if it exceeds a designated threshold value.

BACKGROUND

The present invention relates generally to a method, system, and computer program product for processing of digital recordings. More particularly, the present invention relates to a method, system, and computer program product for cognitive encapsulation of group meetings.

Meetings with groups that include supervisors and coworkers are often held as part of the ordinary course of business. In some cases, a meeting may be one of a series of related meetings. For example, a group may be involved in a large project that is ongoing for several weeks, months, or years. This group may meet from time to time to discuss various aspects of the project. These meetings can be considered to be a series of related meetings. Alternatively, a group may be involved in a specific aspect of a business, such as accounting or marketing. This group may meet from time to time to discuss various aspects of some such aspect of the business. These meetings can also be considered to be a series of related meetings.

In some situations, a group may participate in electronic meetings, also known as web conferences. Web conferences may be interactions among individuals facilitated by electronic means, such as a web conference system. For example, a web conference system may facilitate speech-, text-, and/or video-enabled communication sessions among a plurality of individuals. Certain web conferences may include presentation of audio-visual (and/or other) content to meeting participants in addition/as an alternative to speech, text, and/or video communication. For example, certain web conference systems may permit meeting participants to view and/or control the presentation of various slides and/or other content. Web conferences allow for meetings between two or more individuals who are located in different locations such that an in-person meeting may not be practical. Web conferences allow a meeting to be conducted virtually such that the two or more participants interact with one another remotely.

SUMMARY

DETAILED DESCRIPTION

Generally, a meeting involves an oral presentation or discussion of one or more topics with live and/or remote attendance of conference participants. Oftentimes, multiple meeting participants may provide oral input during the conference. Sometimes a meeting is one of a series of related meetings. A series of “related meetings” as referred to herein may be any two or more meetings involving a common topic or related topics, such as meetings related to an ongoing project or meeting related to a particular department or other aspect of a business. Such meetings may include groups of people meeting in person and/or meeting remotely using a web conference system. Unless otherwise indicated, the term “meeting” as used herein refers to both in-person meetings and web conferences. Also, a “web conference” as used herein refers to any meeting that involves the use of an electronic system that facilitates speech-, text-, and/or video-enabled communication among a plurality of meeting participants.

Sometimes it is not possible for a meeting invitee to participate in a meeting. By not attending the meeting, the invitee is unable to efficiently obtain information from the meeting and may miss important information conveyed during the meeting. Sometimes a meeting may be recorded or a meeting participant may be assigned to record the minutes of the meeting or generate a meeting summary. However, while meeting minutes or summaries prepared by a participant may be helpful in some ways, they may miss important details, and typically do not include non-verbal cues, such as the attentiveness of other participants during the meeting or particular topics, or the energy involved in debating a particular topic, which can also be meaningful by imparting a level of interest or importance for the topic or meeting as a whole. A recording of a meeting can be very time consuming to review, and may miss aspects of a meeting, such as an audio recording in which meeting participants refer to a visual presentation, chart, diagram, or other visual aid. Importantly, a digital recording of a meeting typically includes valuable data that is underutilized when stored for the sole purpose of review by invitees that missed the meeting.

The illustrated embodiments address these issues by providing for cognitive encapsulation of group meetings. Exemplary embodiments leverage artificial intelligence (AI) techniques on digital recordings of meetings, which may include audio or video data, to perform various administrative tasks. The administrative tasks include tasks performed on during or after a meeting to update various types of administrative data. Examples of AI techniques utilized by exemplary embodiments to improve the usefulness of the digital recording data include AI processing to identify meeting participants that have leadership roles, AI processing to identify topics discussed during meetings, AI processing to identify action items discussed during meetings and update action items as they are discussed across a series of meetings, AI processing to identify debates and opinions expressed during meetings, AI processing to detect the attentiveness of meeting participants during meetings, AI processing to find media items related to action items that might be helpful to the meeting participants in performing the associated tasks, and summary reporting in which the contents and recipients of summaries is based on AI processing of the digital recording of the meeting.

Illustrative embodiments that provide for cognitive encapsulation of a meeting allow for segmenting audio feed data into a plurality of clusters. In some embodiments, the clusters correspond with respective meeting participants recorded during the meeting such that the number of clusters equals the number of meeting participants who were recorded speaking during the meeting. Some embodiments allow for identifying which meeting participant is speaking in each cluster, for example by detecting a self-introduction by the speaker in the audio data of the cluster.

Some exemplary embodiments allow for AI processing of digital recordings of meetings to detect meeting participants who have leadership roles, such as managers, team leaders, or other supervisory roles. In some such embodiments, leader detection is based on one or more scoring techniques involving analysis of the digital recording of the meeting, such as a preliminary leadership score based on audio features (e.g., speaking duration and/or interjections) and another preliminary leadership score based on video analysis of meeting participants, and a final leadership score based on one or more preliminary leadership scores. Some such embodiments allow for a computerized system that automatically generates a recipient list for a supervisory-level summary report of the meeting using the results of the leadership detection.

Some exemplary embodiments allow for AI processing of digital recordings of meetings to identify action items discussed during meetings. Some such embodiments allow for tracking the life cycle of action items across multiple meetings. In some embodiments, a digital recording of a meeting undergoes AI processing to extract certain entities and certain sets of relationships between those entities from speech content in the digital recording. The term “entities” as used herein refer to words or phrases that are included in a class of words and phrases that are indicative of an action item based on meaning and usage or context, making them identifiable by a trained machine learning model as being related to an action item, such as a participant name, a date, or a task.

In some embodiments, tasks may be identifiable by a trained machine learning model that is trained using a corpus of transcripts of past meetings, allowing the machine learning model to learn to identify words and phrases classified as tasks, and words and phrases classified as action items. Some such embodiments generate a list of current action items based on the extracted entities and relationships between entities from a digital recording of a most recent meeting. Some such embodiments allow for updating a progress list that includes ongoing action items discussed during past meetings with updates of those action items discussed during the most recent meeting, as well as adding new action items from the most recent meeting that were not previously discussed and therefore not previously present on the progress list. Some such embodiments allow for a computerized system that automatically generates a progress report that includes statuses of action items on the progress list as updated from the most recent meeting.

In some embodiments, a clustering process receives or accesses digital recordings of meetings and partitions the recordings into clusters of segments. In some embodiments, the clustering process performs a speaker diarization process of partitioning a digital recording into clusters of segments according to speaker identity. Embodiments of the clustering process may use any of a variety of technologies to partition digital recordings of meetings into speaker-based clusters. As a non-limiting example, some embodiments of the clustering process analyze a digital recording of a meeting to partition the recording into clusters and group the clusters into hypothesized speakers using a machine-learning clustering scheme, such as Agglomerative Hierarchical Clustering (AHC) or Spectral clustering (SC).

In some embodiments, a cluster verification process verifies that the number of clusters is equal to the number of meeting participants that spoke during the meeting. If the cluster verification process detects that the plurality of clusters is not equal in number to the plurality of participants, the cluster verification process signals the clustering process to repeat the clustering process in a different manner to correct the mismatch between the number of clusters and the number of speaking meeting participants.

In some embodiments, a model adjustment process is performed in conjunction with the clustering process and the cluster verification process to perform a model adjustment process until the number of clusters is satisfactory. In some embodiments, the model adjustment process includes performing one or more iterations of (a) performing the model adjustment process to adjust model parameters used for clustering, (b) performing the clustering process using the adjusted parameters to partition a recording into clusters, and (c) performing the cluster verification process to determine whether the number of clusters is satisfactory; if not, the processes are repeated until the number of clusters is satisfactory.

In some such embodiments, the cluster verification process receives the initially-clustered digital recording from the clustering process and determines whether the number of clusters is satisfactory based on whether the number of clusters is the same as the number of meeting participants who spoke while the meeting was being recorded. In some such embodiments, the cluster verification process determines the number of meeting participants who spoke while the meeting was being recorded in a variety of ways, for example from user input or as metadata that accompanies the recording of the meeting. In some embodiments, the cluster verification process receives a number of meeting participants and uses this as the number of speakers based on an underlying presumption that each meeting participant spoke at least once.

If the cluster verification process determines the number of clusters is not satisfactory, this result triggers the model adjustment process to adjust one or more parameters of the model used by the clustering process for the machine-learning clustering scheme. There are a variety of clustering schemes that may be used in actual implementations, so the actual model parameters, parameter values, and parameter adjustments are implementation specific.

Once the model adjustment process has completed the parameter adjustment, this triggers the clustering process to repeat the clustering of the digital recording of a meeting. The clustering process then provides the number of clusters to the clustering process to again determine whether the number of clusters is satisfactory. If not, then the parameters are readjusted and the recording is re-clustered again, and this continues until the number of clusters is satisfactory.

In some embodiments, a transcription process analyzes the audio of a digital recording of a meeting, including using speech recognition technology to retrieve the speech content of the audio. In some embodiments, the transcription process uses speech-to-text NLP algorithms to generate a text transcription of the incoming audio. The transcription process then provides the text transcription to other processes that may make use of the text transcription, such as a leader identification process or an action item identification process. In some embodiments, the transcription process stores the text transcription in memory, such as a database.

In some embodiments, a cluster labeling process generates metadata or header data for each cluster indicative of a meeting participant associated with that cluster. In some embodiments, the data added by the cluster labeling process is based on system settings, which may be set according to default or user preferences. In some embodiments, the cluster labeling process receives the speaker identity information from an identification process and associates the speaker identity information with the respective associated cluster, for example as metadata or header data.

It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.

Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.

Referring now to FIG. 1 , illustrative cloud computing environment 50 is depicted. As shown, cloud computing environment 50 includes one or more cloud computing nodes 10 with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone 54A, desktop computer 54B, laptop computer 54C, and/or automobile computer system 54N may communicate. Nodes 10 may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment 50 to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices 54A-N shown in FIG. 1 are intended to be illustrative only and that computing nodes 10 and cloud computing environment 50 can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).

Referring now to FIG. 2 , a set of functional abstraction layers provided by cloud computing environment 50 (FIG. 1 ) is shown. It should be understood in advance that the components, layers, and functions shown in FIG. 2 are intended to be illustrative only and embodiments of the invention are not limited thereto. As depicted, the following layers and corresponding functions are provided:

Hardware and software layer 60 includes hardware and software components. Examples of hardware components include: mainframes 61; RISC (Reduced Instruction Set Computer) architecture based servers 62; servers 63; blade servers 64; storage devices 65; and networks and networking components 66. In some embodiments, software components include network application server software 67 and database software 68.

Virtualization layer 70 provides an abstraction layer from which the following examples of virtual entities may be provided: virtual servers 71; virtual storage 72; virtual networks 73, including virtual private networks; virtual applications and operating systems 74; and virtual clients 75.

In one example, management layer 80 may provide the functions described below. Resource provisioning 81 provides dynamic procurement of computing resources and other resources that are utilized to perform tasks within the cloud computing environment. Metering and Pricing 82 provide cost tracking as resources are utilized within the cloud computing environment, and billing or invoicing for consumption of these resources. In one example, these resources may include application software licenses. Security provides identity verification for cloud consumers and tasks, as well as protection for data and other resources. User portal 83 provides access to the cloud computing environment for consumers and system administrators. Service level management 84 provides cloud computing resource allocation and management such that required service levels are met. Service Level Agreement (SLA) planning and fulfillment 85 provide pre-arrangement for, and procurement of, cloud computing resources for which a future requirement is anticipated in accordance with an SLA.

Workloads layer 90 provides examples of functionality for which the cloud computing environment may be utilized. Examples of workloads and functions which may be provided from this layer include: mapping and navigation 91; software development and lifecycle management 92; virtual classroom education delivery 93; data analytics processing 94; transaction processing 95; and experience encapsulation processing 96.

With reference to FIG. 3 , this figure depicts a block diagram of an example service infrastructure 300 that includes an experience encapsulation system 310 in accordance with an illustrative embodiment. In some embodiments, the experience encapsulation system 310 is deployed in workloads layer 90 of FIG. 2 . By way of example, in some embodiments, experience encapsulation system 310 is implemented as experience encapsulation processing 96 in FIG. 2 .

In the illustrated embodiment, the service infrastructure 300 provides services and service instances to a user device 304 and an associated web conference system 312. User device 304 and web conference system 312 communicate with service infrastructure 300 via an API gateway 306. In various embodiments, service infrastructure 300 and its associated experience encapsulation system 310 serve multiple users and multiple tenants. A tenant is a group of users (e.g., a company) who share a common access with specific privileges to the software instance. Service infrastructure 300 ensures that tenant specific data is isolated from other tenants.

In some embodiments, user device 304 and web conference system 312 connect with API gateway 306 via any suitable network or combination of networks such as the Internet, etc. and use any suitable communication protocols such as Wi-Fi, Bluetooth, etc. Service infrastructure 300 may be built on the basis of cloud computing. API gateway 306 provides access to client applications like experience encapsulation system 310. API gateway 306 receives service requests issued by client applications, and creates service lookup requests based on service requests. As a non-limiting example, in an embodiment, the user device 304 executes a routine to initiate transmission of an audio and/or video feed from the web conference system 312 to the experience encapsulation system 310 for experience encapsulation processing.

In the illustrated embodiment, service infrastructure 300 includes a service registry 308. In some embodiments, service registry 308 looks up service instances of experience encapsulation system 310 in response to a service lookup request such as one from API gateway 306 in response to a service request from user device 304. For example, in some embodiments, the service registry 308 looks up service instances of experience encapsulation system 310 in response to requests related to experience encapsulation processing from the user device 304.

In some embodiments, the service infrastructure 300 includes one or more instances of the experience encapsulation system 310. In some such embodiments, each of the multiple instances of the experience encapsulation system 310 run independently on multiple computing systems. In some such embodiments, experience encapsulation system 310, as well as other service instances of experience encapsulation system 310, are registered in service registry 308.

In some embodiments, service registry 308 maintains information about the status or health of each service instance including performance information associated each of the service instances. For example, as described in more detail herein, such performance information may include various types of performance characteristics of a given service instance (e.g., cache metrics, etc.). As described in more detail herein, extended service registry 308 ranks service instances based on their respective performance characteristics, and selects top-ranking service instances for service discovery or service lookup requests. In the event that a service instance becomes unresponsive or, unhealthy, the service registry will no longer provide its address or information about this service instance to other services.

With reference to FIG. 4 , this figure depicts a block diagram of an experience encapsulation system 400 in accordance with an illustrative embodiment. In a particular embodiment, experience encapsulation system 400 is an example of experience encapsulation system 310 of FIG. 3 .

In some embodiments, the experience encapsulation system 400 includes a leader identification module 402, a topic identification module 404, an action item identification module 406, a debate identification module 408, an attentiveness identification module 410, a metadata enrichment module 412, and a summary reporting module 414. In alternative embodiments, the experience encapsulation system 400 can include some or all of the functionality described herein but grouped differently into one or more modules. In some embodiments, the functionality described herein is distributed among a plurality of systems, which can include combinations of software and/or hardware based systems, for example Application-Specific Integrated Circuits (ASICs), computer programs, or smart phone applications.

In the illustrated embodiment, the experience encapsulation system 400 leverages artificial intelligence (AI) techniques on audio or video data acquired during meetings to perform various administrative tasks. The administrative tasks include tasks performed on during or after a meeting to update various types of administrative data. The AI techniques used by various embodiments of the experience encapsulation system 400 include using AI processing of digital recordings of meetings. For example, some embodiments of the experience encapsulation system 400 perform AI processing of digital recordings that includes using AI processing by the leader identification module 402 to identify meeting participants that have leadership roles, using AI processing by the topic identification module 404 to identify topics discussed during meetings, using AI processing by the action item identification module 406 to identify action items discussed during meetings, using AI processing by the debate identification module 408 to identify opinions expressed during meetings, and using AI processing by the attentiveness identification module 410 to detect the attentiveness of meeting participants during meetings. Also, some embodiments of the experience encapsulation system 400 use the metadata enrichment module 412 to find media items related to action items that might be helpful to the meeting participants in performing the associated tasks and use the summary reporting module 414 to generate reports using results from the AI processing by the modules of the experience encapsulation system 400. Some embodiments of the experience encapsulation system 400 also store data resulting from the AI processing by the modules of the experience encapsulation system 400 in a database 416.

With reference to FIG. 5 , this figure depicts a block diagram of leader identification module 500 in accordance with an illustrative embodiment. In a particular embodiment, leader identification module 500 is an example of leader identification module 402 of FIG. 4 .

In some embodiments, the leader identification module 500 includes an identification module 502, an audio scoring module 504, a video scoring module 506, a leadership scoring module 508, and a role detection module 510. Various embodiments of the leader identification module 500 may also include one or more of a profiling module 512, a model training module 514, a transcription module 516, a clustering module 518, a cluster verification module 520, a cluster labeling module 522, a model adjustment module 524, and a video processing module 526. In alternative embodiments, the leader identification module 500 can include some or all of the functionality described herein but grouped differently into one or more modules. In some embodiments, the functionality described herein is distributed among a plurality of systems, which can include combinations of software and/or hardware based systems, for example Application-Specific Integrated Circuits (ASICs), computer programs, or smart phone applications.

In the illustrated embodiment, the leader identification module 500 provides AI processing of digital recordings of meetings to identify meeting participants that have leadership roles. For example, in the illustrated embodiment, the leader identification module 500 receives an audio or video signal of a meeting from web conference system 312 either during or after the meeting. The audio or video signal is stored as a digital recording where it can be accessed by the leader identification module 500.

In some embodiments, the leader identification module 500 receives digital recordings that have already been partitioned into clusters of segments. For example, in some embodiments, a digital recording undergoes a speaker diarization process of partitioning an input audio stream into clusters of segments according to speaker identity.

Alternatively, in some embodiments, the leader identification module 500 includes a clustering module 518 that receives or accesses digital recordings of meetings and partitions the recordings into clusters of segments. In some embodiments, the clustering module 518 performs a speaker diarization process of partitioning a digital recording into clusters of segments according to speaker identity. Embodiments of the clustering module 518 may use any of a variety of technologies to partition digital recordings of meetings into speaker-based clusters. As a non-limiting example, some embodiments of the clustering module 518 process a digital recording of a meeting to partition the recording into clusters and group the clusters into hypothesized speakers using a machine-learning clustering scheme, such as Agglomerative Hierarchical Clustering (AHC) or Spectral clustering (SC).

In some embodiments, the leader identification module 500 includes additional clustering support modules for testing and performing administrative tasks related to the clusters created by the clustering module 518. For example, in some embodiments, the leader identification module 500 includes a cluster verification module 520, a cluster labeling module 522, and/or a model adjustment module 524.

In the illustrated embodiment, the cluster verification module 520 verifies that the number of clusters is equal to the number of meeting participants that spoke during the meeting. If the cluster verification module 520 detects that the plurality of clusters is not equal in number to the plurality of participants, the cluster verification module 520 signals the clustering module 518 to repeat the clustering process in a different manner to correct the mismatch between the number of clusters and the number of speaking meeting participants.

In some embodiments, the leader identification module 500 includes both the cluster verification module 520 and the model adjustment module 524, and the leader identification module 500 controls the clustering module 518, cluster verification module 520, and model adjustment module 524 to perform a model adjustment process until the number of clusters is satisfactory. In some embodiments, the model adjustment process includes performing one or more iterations of (a) controlling the model adjustment module 524 to adjust model parameters used for clustering, (b) controlling the clustering module 518 to use the parameters to partition a recording into clusters, and (c) controlling the cluster verification module 520 to determine whether the number of clusters is satisfactory; if not, the process is repeated; if so, the process ends.

In some such embodiments, the cluster verification module 520 receives the initially-clustered digital recording from the clustering module 518 and determines whether the number of clusters is satisfactory. If not, then the leader identification module 500 initiates the model adjustment process. In some such embodiments, the cluster verification module 520 determines the number of clusters to be satisfactory if the number of clusters is the same as the number of meeting participants who spoke while the meeting was being recorded. In some such embodiments, the cluster verification module 520 determines the number of meeting participants who spoke while the meeting was being recorded in a variety of ways, for example from user input or as metadata that accompanies the recording of the meeting. In some embodiments, the cluster verification module 520 receives a number of meeting participants and uses this as the number of speakers based on an underlying presumption that each meeting participant spoke at least once.

If the cluster verification module 520 determines that number of clusters is not satisfactory, this result triggers the model adjustment module 524 to adjust one or more parameters of the model used by the clustering module 518 for the machine-learning clustering scheme. There are a variety of clustering schemes that may be used in actual implementations, so the actual model parameters, parameter values, and parameter adjustments are implementation specific.

Once the model adjustment module 524 has completed the parameter adjustment, this triggers the clustering module 518 to repeat the clustering of the digital recording of a meeting. The clustering module 518 then provides the number of clusters to the clustering module 518 to again determine whether the number of clusters is satisfactory. If not, then the parameters are readjusted and the recording is re-clustered again, and this continues until the number of clusters is satisfactory.

The identification module 502 receives or accesses digital recordings of meetings to associate audio from the meeting with meeting participants. The audio in digital recordings of meetings will primarily include recordings of meeting participants speaking during the meeting. The identification module 502 uses AI processing to identify which meeting participant is speaking and associate the speaking participant with the recording. In some embodiments, the identification module 502 processes individual clusters of digital recordings after the recordings have been partitioned into clusters of segments according to speaker identity. As the identification module 502 processes a cluster, it identifies which meeting participant is speaking in the cluster and associate the speaking participant with that cluster of the recording.

Embodiments of the identification module 502 may use any of a variety of automatic speech recognition technologies that enable the recognition of spoken language into text by computers. As an example, some embodiments of the identification module 502 use Natural language processing (NLP) technology, such as a Hidden Markov Model (HMM) or a Deep Neural Network (DNN).

In the illustrated embodiment, the leader identification module 500 includes a transcription module 516 that analyzes the audio of a digital recording of a meeting, including using speech recognition technology to retrieve the speech content of the audio. In some embodiments, the transcription module 516 uses speech-to-text NLP algorithms to generate a text transcription of the incoming audio. The transcription module 516 then provides the text transcription to the identification module 502, as well as any other modules that may make use of the text transcription. In some embodiments, the transcription module 516 stores the text transcription in memory, such as the database 416 of FIG. 4 .

The identification module 502 receives or accesses the text transcription generated by the transcription module 516 and uses a DNN to process the text transcription, for example by extracting features of the dialogue (e.g., to identify tone, sentiment, etc.), eliminating noise, and identifying references to the identity of the speaker. Non-limiting examples of references to the speaker's identity that the DNN may extract include a self-introduction by the speaker or a response by the speaker to a prompt from another meeting participant (e.g., asking a question or inviting to begin a presentation) where the prompt includes identity information. In some embodiments, the identification module 502 stores the speaker names associated with each cluster in memory, such as the database 416 of FIG. 4 .

In the illustrated embodiment, the leader identification module 500 includes a cluster labeling module 522. In some embodiments, the cluster labeling module 522 generates metadata or header data for each cluster. In some embodiments, the data added by the cluster labeling module 522 is based on system settings, which may be set according to default or user preferences. In some embodiments, the cluster labeling module 522 receives the speaker identity information from the identification module 502 and associates the speaker identity information with the respective associated cluster, for example as metadata or header data.

In the illustrated embodiment, the audio scoring module 504 generates a first preliminary leadership score for each of the meeting participants based on audio features in the digital recording of the incoming audio. In some embodiments, the audio scoring module 504 generates a first preliminary leadership score for each of the meeting participants on a cluster by cluster basis, such that the audio scoring module 504 processes one of the clusters generated by the clustering module 518 at a time. In some such embodiments, the audio scoring module 504 receives or accesses a cluster for scoring, generates first preliminary leadership score for that cluster, and associates the generated first preliminary leadership score the meeting participant associated with the cluster (e.g., based on speaker identity information that the cluster labeling module 522 associated with the cluster).

In the illustrated embodiment, the leader identification module 500 includes a profiling module 512, and the audio scoring module 504 generates a first preliminary leadership score for each of the meeting participants based on audio features as determined by the profiling module 512. In some embodiments, when the audio scoring module 504 receives or accesses a cluster for scoring, the audio scoring module 504 triggers the profiling module 512 to evaluating that cluster. In some embodiments, the profiling module 512 calculates a speaking duration value for the cluster, for example based on the size of the cluster and information in the technical metadata of the cluster, such as file type or format, bit depth, sample rate, bit depth, and number of tracks. In some embodiments, the profiling module 512 calculates an interjection value for the cluster, for example based on the number of interjections detected in the cluster. For example, in some embodiments, the 512 detects instances of multiple participants speaking at the same time in the audio and filters those to include only instances where the speaker of the current cluster is beginning to speak while another participant has been speaking, and those instances remaining are identified as an interruption and counted as an interjection.

In some embodiments, the profiling module 512 provides audio feature information to the audio scoring module 504 for each cluster as the profiling module 512. For example, the audio feature information may include one or more values based at least in part on the speaking duration and/or interjection values determined by the profiling module 512. In such embodiment, the audio scoring module 504 generates the first preliminary leadership score based on the audio feature information received by the profiling module 512. In some embodiments, the audio scoring module 504 uses the amount of time speaking and/or the number of interjections as a first preliminary leadership score for each meeting participant. In some embodiments, the audio scoring module 504 uses the amount of time speaking and/or the number of interjections to calculate a first preliminary leadership score, for example by accounting for the total length of the meeting in order to normalize the scores across a series of meetings having different durations. In some embodiments, the audio scoring module 504 stores the first preliminary leadership score for each meeting participant in memory, such as the database 416 of FIG. 4 .

In the illustrated embodiment, the video scoring module 506 generates a second preliminary leadership score for each of the meeting participants based AI processing of video elements of the digital recording of a meeting. The video scoring module 506 receives or accesses video segments from the digital recording of the meeting and synchronizes the video segments with the segmented audio from the digital recording.

In the illustrated embodiment, the video scoring module 506 receives the video segments from the video processing module 526. In some such embodiments, the video processing module 526 partitions video from the digital recording of the meeting into a plurality of video segments. In some embodiments, the video processing module 526 partitions the video such that the segments are temporally aligned with the clusters generated by the clustering module 518. In some such embodiments, the video processing module 526 receives the speaker identity information from the identification module 502 for each cluster, associates the speaker identity information with the video segments based on the speaker associated with the corresponding audio cluster, for example as metadata or header data of each video segment.

In some embodiments, the video scoring module 506 evaluates each video segment using a DNN or other processes to output respective scores indicative of the associated participant's role (e.g., leader or non-leader role). In some such embodiments, the DNN includes a machine learning classifier model that is trained by model training module 514. In some embodiments, the model training module 514 trains the machine learning classifier model using training data that includes features of video of a past meetings. For example, in some such embodiments, the model training module 514 uses a meeting corpus to identify visual indicators in the video frames of meeting participants that causes them to be classified as having leadership roles or non-leadership roles.

In some embodiments, video scoring module 506 uses the output score from the DNN as a second preliminary leadership score for each meeting participant. In some embodiments, the video scoring module 506 uses the output score from the DNN to calculate a second preliminary leadership score, for example by accounting for the total length of the meeting in order to normalize the scores across a series of meetings having different durations. In some embodiments, the video scoring module 506 stores the second preliminary leadership score for each meeting participant in memory, such as the database 416 of FIG. 4 .

In the illustrated embodiment, the leadership scoring module 508 calculates a final leadership score for each meeting participant based on the participant's first preliminary leadership score from the audio scoring module 504 and the participant's second preliminary leadership score from the video scoring module 506. The final leadership score is representative of a likelihood that the associated participant is a supervisor or in some other leadership role. In some embodiments, the leadership scoring module 508 calculates the final leadership score based on a weighted average of the first preliminary leadership score and the second preliminary leadership score. The leadership scoring module 508 then stores the results for each participant in memory, such as the database 416 of FIG. 4 .

In the illustrated embodiment, the role detection module 510 evaluates the leadership score for each meeting participant to determine how to classify them. In some embodiments, the role detection module 510 compares the final leadership score from the leadership scoring module 508 to a threshold value, and the outcome of the comparison is indicative of whether the participant is classified as a leader or non-leader. In some embodiments, the threshold value is preset or hard-coded in the role detection module. Alternatively, in some embodiments, a user can set or adjust the threshold value.

In the illustrated embodiment, the summary reporting module 414 generates a supervisory report that includes a summary of the meeting for which the leader identification module 500 has been processing a digital recording. In an embodiment, the supervisory report is only sent or made available to meeting participants identified as leaders by the role detection module 510. In some embodiments, the role detection module 510 provides the list of participants identified as leaders to the summary reporting module 414, which in turn sends supervisory reports, or notifications of the availability of supervisory reports, to participants on the list from the role detection module 510.

With reference to FIG. 6 , this figure depicts a block diagram of an action item identification module 600 in accordance with an illustrative embodiment. In a particular embodiment, the action item identification module 600 is an example of the action item identification module 406 of FIG. 4 .

In some embodiments, the action item identification module 600 includes an entity-relation extraction module 602, a current listing module 604, a list comparison module 606, and a progress list updating module 608. Various embodiments of the action item identification module 600 may also include one or more of a model adjustment module 610, a transcription module 612, a model training module 614, a clustering module 616, a cluster verification module 618, and a cluster labeling module 620. In alternative embodiments, the action item identification module 600 can include some or all of the functionality described herein but grouped differently into one or more modules. In some embodiments, the functionality described herein is distributed among a plurality of systems, which can include combinations of software and/or hardware based systems, for example Application-Specific Integrated Circuits (ASICs), computer programs, or smart phone applications.

In the illustrated embodiment, the action item identification module 600 provides AI processing of digital recordings of meetings to identify action items discussed during meetings. In some embodiments, the action item identification module 600 keeps track of the life cycle of action items across multiple meetings. In the illustrated embodiment, the action item identification module 600 receives an audio or video signal of a meeting from web conference system 312 either during or after the meeting. The audio or video signal is stored as a digital recording where it can be accessed by the action item identification module 600.

In some embodiments, the action item identification module 600 receives digital recordings that have already been partitioned into clusters of segments. For example, in some embodiments, a digital recording undergoes a speaker diarization process of partitioning an input audio stream into clusters of segments according to speaker identity.

Alternatively, in some embodiments, the action item identification module 600 includes a clustering module 616 that receives or accesses digital recordings of meetings and partitions the recordings into clusters of segments. In some embodiments, the clustering module 616 performs a speaker diarization process of partitioning a digital recording into clusters of segments according to speaker identity. Embodiments of the clustering module 616 may use any of a variety of technologies to partition digital recordings of meetings into speaker-based clusters. As a non-limiting example, some embodiments of the clustering module 616 process a digital recording of a meeting to partition the recording into clusters and group the clusters into hypothesized speakers using a machine-learning clustering scheme, such as Agglomerative Hierarchical Clustering (AHC) or Spectral clustering (SC).

In some embodiments, the action item identification module 600 includes additional clustering support modules for testing and performing administrative tasks related to the clusters created by the clustering module 616. For example, in some embodiments, the action item identification module 600 includes a cluster verification module 618, a cluster labeling module 620, and/or a model adjustment module 610.

In the illustrated embodiment, the cluster verification module 618 verifies that the number of clusters is equal to the number of meeting participants that spoke during the meeting. If the cluster verification module 618 detects that the plurality of clusters is not equal in number to the plurality of participants, the cluster verification module 618 signals the clustering module 616 to repeat the clustering process in a different manner to correct the mismatch between the number of clusters and the number of speaking meeting participants.

In some embodiments, the action item identification module 600 includes both the cluster verification module 618 and the model adjustment module 610, and the action item identification module 600 controls the clustering module 616, cluster verification module 618, and model adjustment module 610 to perform a model adjustment process until the number of clusters is satisfactory. In some embodiments, the model adjustment process includes performing one or more iterations of (a) controlling the model adjustment module 610 to adjust model parameters used for clustering, (b) controlling the clustering module 616 to use the parameters to partition a recording into clusters, and (c) controlling the cluster verification module 618 to determine whether the number of clusters is satisfactory; if not, the process is repeated; if so, the process ends.

In some such embodiments, the cluster verification module 618 receives the initially-clustered digital recording from the clustering module 616 and determines whether the number of clusters is satisfactory. If not, then the action item identification module 600 initiates the model adjustment process. In some such embodiments, the cluster verification module 618 determines the number of clusters to be satisfactory if the number of clusters is the same as the number of meeting participants who spoke while the meeting was being recorded. In some such embodiments, the cluster verification module 618 determines the number of meeting participants who spoke while the meeting was being recorded in a variety of ways, for example from user input or as metadata that accompanies the recording of the meeting. In some embodiments, the cluster verification module 618 receives a number of meeting participants and uses this as the number of speakers based on an underlying presumption that each meeting participant spoke at least once.

If the cluster verification module 618 determines that number of clusters is not satisfactory, this result triggers the model adjustment module 610 to adjust one or more parameters of the model used by the clustering module 616 for the machine-learning clustering scheme. There are a variety of clustering schemes that may be used in actual implementations, so the actual model parameters, parameter values, and parameter adjustments are implementation specific.

Once the model adjustment module 610 has completed the parameter adjustment, this triggers the clustering module 616 to repeat the clustering of the digital recording of a meeting. The clustering module 616 then provides the number of clusters to the clustering module 616 to again determine whether the number of clusters is satisfactory. If not, then the parameters are readjusted and the recording is re-clustered again, and this continues until the number of clusters is satisfactory.

In some embodiments, the entity-relation extraction module 602 receives or accesses digital recordings of meetings and uses AI processing to identify a set of designated entities and a set of relationships between designated entities from speech content of the digital recordings. For example, in some embodiments, the set of designated entities comprises participants, tasks, and dates. Also, in some embodiments, the set of relationships between designated entities comprises associations between tasks and participants and associations between tasks and dates. In some embodiments, the entity-relation extraction module 602 processes individual clusters of digital recordings after the recordings have been partitioned into clusters of segments according to speaker identity. As the entity-relation extraction module 602 processes a cluster, it identifies which meeting participant is speaking in the cluster and associate the speaking participant with that cluster of the recording.

Embodiments of the entity-relation extraction module 602 may use any of a variety of automatic speech recognition technologies that enable the recognition of spoken language into text by computers. For example, some embodiments of the entity-relation extraction module 602 use Named-Entity Recognition (NER) processing using statistical modeling, such as maximum entropy (MaxEnt) or conditional random fields (CRF), to locate and classify named entities mentioned in the text of each cluster. In some embodiments, the entity-relation extraction module 602 uses Natural language processing (NLP) technology, such as a Hidden Markov Model (HMM) or a Deep Neural Network (DNN).

In the illustrated embodiment, the leader identification module 500 includes a transcription module 612 that analyzes the audio of a digital recording of a meeting, including using speech recognition technology to retrieve the speech content of the audio. In some embodiments, the transcription module 612 uses speech-to-text NLP algorithms to generate a text transcription of the incoming audio. The transcription module 612 then provides the text transcription to the entity-relation extraction module 602, as well as any other modules that may make use of the text transcription. In some embodiments, the transcription module 612 stores the text transcription in memory, such as the database 416 of FIG. 4 .

The entity-relation extraction module 602 receives or accesses the text transcription generated by the transcription module 516 and uses a DNN to process the text transcription, for example by classifying parts of speech content, eliminating noise, and identifying references to action items. Non-limiting examples of references to action items that the DNN may extract include references to participants, tasks, and/or dates. In some embodiments, the entity-relation extraction module 602 stores the extracted data associated with action items in memory, such as the database 416 of FIG. 4 .

In some such embodiments, the DNN includes a machine learning classifier model that is trained by model training module 614. In some embodiments, the model training module 614 trains the machine learning classifier model using training data that includes features of audio of a past meetings. For example, in some such embodiments, the model training module 614 uses a meeting corpus to identify audio indicators in the audio of meeting participants that causes them to be classified as an entity (e.g., participants, tasks, and dates) or an indicator of a relationship between entities (e.g., associations between tasks and participants and associations between tasks and dates).

In the illustrated embodiment, the action item identification module 600 includes a cluster labeling module 620. In some embodiments, the cluster labeling module 620 generates metadata or header data for each cluster. In some embodiments, the data added by the cluster labeling module 620 is based on system settings, which may be set according to default or user preferences. In some embodiments, the cluster labeling module 620 receives the speaker identity information from the leader identification module 500 and associates the speaker identity information with the respective associated cluster, for example as metadata or header data.

In some embodiments, the current listing module 604 generate a list of current action items based on the extracted set of designated entities and the set of relationships between designated entities. The current listing module 604 then provides this current action items list to the list comparison module 606.

In some embodiments, the list comparison module 606 identifies which action items on the current action items list are also on a progress list, which is a list of ongoing action items from past meetings prior to the current meeting. In some embodiments, the list comparison module 606 also identifies which action items on the current action items list are not on the progress list.

In some embodiments, the progress list updating module 608 updates the progress list based on the results of the processing by the list comparison module 606. The progress list updating module 608 updates the progress list updating action items identified by the list comparison module 606 as being both on the current action items list and on the progress list such that the progress list has updates from the current meeting. The remaining action items are considered new action items, so the progress list updating module 608 updates the progress list by adding the new action items to the progress list.

In the illustrated embodiment, the summary reporting module 414 generates a supervisory report that includes a summary of the meeting for which the action item identification module 600 has been processing a digital recording. In an embodiment, the supervisory report is only sent or made available to meeting participants identified as leaders by the leader identification module 500. In some embodiments, the supervisory report includes a summary of the action items on the progress list, including a summary of updates made to the progress list by the action item identification module 600.

In a particular embodiment, the summary reporting module 414 carries out the process 1300.

In an embodiment, at block 1302, the process determines whether the current summary is a supervisory report or a general report. If general, the process continues to block 1304, where the process receives transcripts of all meeting participants, for example from a transcription module 516 of FIG. 5 or a transcription module 612 of FIG. 6 . Next, at block 1306, the process combines transcripts using temporal metadata.

On the other hand, if the summary is supervisory level, then at block 1310 the process retrieves only transcripts of leaders during the meeting, for example from a transcription module 516 of FIG. 5 or a transcription module 612 of FIG. 6 .

Next, at block 1308, the process eliminates stop words from the transcipt(s) (e.g., a, an, the, etc.). Next, at block 1312, the process tokenizes the remaining transcript data into sentences, and at block 1314, the process creates sentence embeddings using pretrained machine learning models. At block 1316, the process clusters the embeddings into a summary using the number of clusters as an indicator of a number of sentences to use for the summary.

ROM 1524 may be, for example, a flash binary input/output system (BIOS). Hard disk drive 1526 and CD-ROM 1530 may use, for example, an integrated drive electronics (IDE), serial advanced technology attachment (SATA) interface, or variants such as external-SATA (eSATA) and micro-SATA (mSATA). A super I/O (SIO) device 1536 may be coupled to South Bridge and I/O controller hub (SB/ICH) 1504 through bus 1538.
